Thisinvention relates .to an improvement in tools for use in severin the like to shorten or produce a screw, or the like of the desired length;

The object of the invention is to provide screws, bolts or bolt :1- tool of this character especially designedfor use in conjunction with-threaded parts so as to enable a portion of the screw or threadedbolt to be cut off to produce the dc sired length of the screw or bolt without inscrew intended tobeused.

Another object is to provide a tool of this character and having t ese advantages and capacities and which greatly facilitates the operation of severing the screw, bolt or the like, and which is also of simple and durable construction,reliable in operation and easy and inexpensive to manufacture.

' Other ob ects and advantages of the nvention reside in certain novel features of the construction, combination and arrange ment of parts which will be hereinafter more fully described and particularly poi-ited out in .the appended claims, reference beinghad to the accompanying drawings forming part of this specification, and'iii which:

Figure 1 is a. view in side elevation, showing one embodiment of the invention;

Figure 2 is a view thereofin top plan;.

Figure 3 .is .a plan view of one of. the members of the tool;

Figure 4 is a view showing the manner in and with the screw, bolt or the like;

Figure 5 is a. detailed perspective view of the stop or device employed for preventing axial movement of the screw, bolt or the like. Referring to the drawings it will be seen that the tool comprises a pair of members pivotally connected toeach other as at 11 and having handles 12 whereby the members may be swung of jaws designate at 13 are provided on the members 10 and each pair of jaws 13 are formed with a plurality of complementary thread engaging faces 1 or, recesses '14. The com lementa thread engagin faces14 are of ifi'erent sizes to accommodate different sized bolts, summer the like. Each face 14 is of uniform width from end to end as clearly shown in Fig. 3 and is also formed with a lengthwise slot 15 which enhances the gripping actionof the face. As shown in the rawings the complementary faces 14 portion of the about the pivot 11. Pairs are'also formed with threads dsignedhto thread engaging faces 14.0f the. size tofit the screw. The portion of the screw which snugly fit and en age the threads of the is intended to be used is engaged by the faces'14. The portion of the'screwwhich is to be removed is gripped'in a vise 'or in any suitable form of pliers, having roughened jaw faces and the screw is then twisted so that it will break off at the point where'it projects from-the tool constituting the pres-. ent- 'lIlVBIlllOIl. The-threaded faces 14 of the tool-are usually adequate to hold the screw againstturning for these faces frictionally engage the threads of the screw and the cdgesprovidedby the slot 15 enhance the gripping action of these faces. In some cases however it has been found-that the screw is turned to some extent relative t the face 14 and of course in order to-tlim It must advance or move axially since the faces 14 of the jaws 13 act as'a nut. I orderto prevent such turning, it is propose to hold the screw against axial movement, and for this purpose the sto or device designated generally at 16 in igures 4 and 5 is provided.

The stop '16 consists of a plurality of thin plates 17 which are of a predetermined thickness and-which are ivotally connected, as at 18. When all oft e plates are alined with-each other, as shown in Figure 4' the openings 19 and 20 of the several plates to receive bolts, screws or the. like of differused in any instance depends on the length are registered. These openings are designed 4 of the screw to be severed. As shown in Figure 4 the plates which are not used areswung away and the screw is passed through the. ali ned openings 19 or 20 of the remaining; plate, the head of the screw being en-' gaged with thetopmost plate. The lower-. most 'plateengages the jawscoacting with the screws. In this wa the stop or device 16 serves to prevent axial movement of the screw, bolt or the like, and as the screw,

.bolt or the like must move'axially in order to turn, the screw, bolt or't-he like is effecjaw faces 14.
